Be it known. that E, LYLE K. SNELL, a citizen of the 'United States anclresident of Detroit, Wayne County State or Micl'iigzan 5 have inventednew and useful 1111- provenients in Supply and Exhaust Menifolcls forInternsl-Combustion Engines, of which the following is a specificationThis invention reletes'to improvements in J hydrocarbon motors,

One of the objects of this invention is to devise on efficienthydrocarbon motor of neat appearance one simple construction.

Another obgect of this invention 1s to pro vi le en eliicicnt heatingdevice for the conv ture of the con'ibustible gases as supplied to ahydrocarbon motor immediately before entering the cylimlers.

Another object of this inventionis to devise e heating device andcontrol for the combustible gases as supplied to s hydrocarbon motorwhich shall be rezulily To moved for cleaning or replacement.

Another object of this invention is to clevise e heating clevice forcombustible gases 39 as supplied to a hydrocarbon motor which shall beconstant antl (lepei'iclsble in operation.

These, and other objects, will more clearly appear from the following.description taken in connection with the accompanying (lraivings which"form a pert of this SPECIfiCntiOH and in which:

Figure 1 is on end elevation of a t type hvdrocerbon motor, with.substantially one half in section to more clearly showthe inventionFigure 2 is e longitudinal section on the line 2-2 in Figure 1.

Referring to the drawings it hydrocarbon 45 motor 10 of v type is shownhovlng the l'iloclzs of cylinders 11 mounted in V relation one to theother on the crank case 12 and having the valves 18 covering the inletand outlet ports as customary in motor construc- 59 tion of the typeshown.

Each block of cylinders 11. has an intake manifold it costintegraltherewith and extenclin along one 51 lo over the inlet ports 15, saiports 15 being hrsncnecteech to two cylinder valve chambers, though mus;he unclerstooii. tl ni't the ports 15 may he of any number orarrangement to suit the cylinder and valve mechanism.

The msniifoitl 14: has an is take 14; midwev of its length and e jscizetcasing; 0' substantially two thircis srouncl the manifold; as shown inFigure 1., though it must he understood such an arrangement is notessentisi and the jacket st parts may be formed around all sides of themsniiolcl. The jacket 16 extends the entire length of the manifold andhas the end inlet and outlet openings 1'? and 18 respectivelv, suiteblvthreaded. The intake illttllli old tlil the. enil next to the outletopening 18 in the jacket has a thrczuleti opening and the enlarged endforming a valve chamber for the valve 21, which is securetl to the outerend. the thermostat rod 22, said i'orl extending; into the-therinostet23, heving one encl aning 19 and extending to the opposite end 0% theintehe manifold where it is supported in on orifice in the boss 25. A.spring 26 is placed between the valve ens {ling bushog :27 screvveclinto the opening 18 in the exhaust jecliiet.

it will be noted that the thermostat extends the entire length of theintake inanifold, past the inlet gorts 15 and as the meni fold is formedin the block with the cylinders 21ml protectecl by the fiecket cesing16, the tein ggernitu're oi the gases Within the nosnifoiol will be thenearest approach to that within the cylinders in which it is possible toadequately arrange a control (levies. Thus the thermostat 23 is placedwhere the control thereof: will be most effective and the after leavingthe manifold will be subjected to a minimum degree of change.

It will be understood that the thermostat when contrectecl, clue to alow temperature, wili permit the spring 26 to move the rocl 22 antivalve Q1 inwardly, opening the space between the valve chamber 20 endthe plug bushing 2'2 21ml also when the thermostat heing in said exhaustjacket in alignment with with said thermostat, a valve secured to 10said thermostat and closing the exhaust jacket about the bushing openingand a spring between said valve and said bushing.

In testimony whereof I aflix my signature.
